Nighttime Lane Closures and Detour on the Dulles Toll Road (DTR), Dulles International Airport Access Highway (DIAAH), Dulles Greenway and Centreville Road for the weekend of Friday, April 29 - Sunday, May 1

Nighttime construction activities will take place over the weekend of Friday, April 29 – Sunday, May 1, causing lane closures on the Dulles Toll Road (DTR), Dulles Greenway and Centreville Road, and a detour on the Dulles International Airport Access Highway (DIAAH)

On or about Friday, April 29, at 10 p.m. to Monday, May 2, at 5 a.m., installation of a Tower Crane at the future Reston Station site will require the closure of the eastbound Dulles International Airport Access Highway (DIAAH) between the Fairfax County Parkway and Reston Parkway as follows:

Just prior to the Fairfax County Parkway, eastbound Dulles International Airport Access Highway (DIAAH) traffic will be diverted to a dedicated left lane on the eastbound Dulles Toll Road (DTR). Approximately 1 mile after entering the Dulles Toll Road (DTR), drivers will then be redirected back onto the eastbound Dulles International Airport Access Highway (DIAAH) near the Reston Parkway overpass. Drivers using this detour will NOT BE REQUIRED TO PAY A TOLL. Drivers are asked to use caution and remain attentive to all signage, barricades and adjusted speed limits. Large, slow-moving vehicles may be exiting and entering the highway at various times.

Please stay alert, obey all signage, and drive carefully. All work is weather permitting and subject to change.
